Remarks to the achievable accuracy The achievable target accuracy depends on end-of-line calibration in the application. Resolution for offset calibration is better than 0.1%Vdd. Trimming capability is higher than measurement accuracy. End-of- line calibration can increase overall system accuracy. |
